/**
 * All DNA is composed of a series of nucleotides abbreviated as A, C, G, and T, for example: "ACGAATTCCG". 
 * When studying DNA, it is sometimes useful to identify repeated sequences within the DNA.
 * Write a function to find all the 10-letter-long sequences (substrings) that occur more than once in a 
 * DNA molecule.For example,Given s = "AAAAACCCCCAAAAACCCCCCAAAAAGGGTTT",Return:
 * ["AAAAACCCCC", "CCCCCAAAAA"].
